I have a feeling MS is going to be doing a Live image update this week because Major Nelson said that he was ready for some new XBLA games (SF2 & Roboblitz???) this week. He couldn't say which ones or when, but he had the list in front of him and they would be out this week*. I hope the TRL demo is on there when they drop the XBLA games.

*Don't hold this to me though; go get his podcast and listen for yourself. It's around the 30 min mark.
